I downloaded the Debian and Ubuntu images for the Zero from the Radxa site. Ran MD5 sums for each of the files and compared them to the published sums. They did not match. Is there an issue?
Here is an example:
*cat radxa-zero-debian-buster-xfce4-arm64-20220210-0524-mbr.img.md5.txt
55b3f876349f55915300eec7df4a3d85 radxa-zero-debian-buster-xfce4-arm64-20220210-0524-mbr.img
md5sum radxa-zero-debian-buster-xfce4-arm64-20220210-0524-mbr.img.xz

Also tried an earlier release:
